Hey there :)
Lets translate the sentences into mathematics:
Contains type a ball = 9
Contains type b ball = 8
Contains type c ball = 3
Total = 9 + 8 + 3 = 20
Type a fraction =
If ball chosen at random is not a type a golf ball
Answer:
Let the total fraction =1
Fraction eaten =½( morning),x(night)
Now,1-(½+x)=1/5
multiply through by LCM 5
5-5/2-5x=1
multiply through again by 2
10-5-10x=2
5-10x=2
5-2=10x
3=10x
x=3/10
So Fluffy ate 3/10 at night
Lets see!
We need to use the pythagorean theorem (a^2+b^2=c^2) to check.
So..
15^2+ 17^2 = 19^2
225+ 289= 361
Hm 225 and 289 do NOT equal 361 therefore it is NOT a right triangle.

ITS THE THRID ONE!
